Root cause: For arrow in presentation, no this issue. Because the basic unit for arrow width is not consistent in Document(twip) and Presentation(100mm). And there is a critical value 2pt(70 100mm, 40 twip) which is used incorrectly for document.
Resolution: Use the critical value as 40 other than 70 for Document arrow width.
Notes: There is a fix for bug 33630. The fix can fix the sample arrow(line width is less than 2pt). But a regression is cause by it. For line width larger than 2pt, they will imported incorrectly(become smaller than MS).
